Patented Oct. 8, 1935 UNITED STATES PATENT OFFICE LO'OM BEAM Gustave Albert Anderson,

Attleboro, Mass., as-

signor to Lewis R. Smith, receiver Apco Mossberg Corporation, a corporation of Rhode Island This invention relates to a loom beam; and has for one of its objects the provision of means forquickly and efliciently adjusting one or both of the heads of a beam along the barrel thereof.

Another object of the invention is the provisionof a clamp which is so mounted that upon actuation the sections of the clamp are moved substantially radially toward the axis of the beam to secure a firm grip upon an extended surface thereof.

Another object of the invention isthe provision of a clamp which may be welded to the head of a beam for securing it in position so that when the clamp is'drawn inwardly to grip the barrel the head will notbe distorted out of the single plane in which it is desired that its surface be presented.

Another object of the invention is the provisionof a clamp, the engaging surface of which floats to a limited extentenabling itto adjust itself to the barrel which it is to engage at the time of its being clamped into engagement therewith.

Another object of the invention isthe provision of a clamp which will possess sufiicient spring. or resilience so that when the parts which holdit in clamping position are released it. will travel radially outwardly to free it" from the barrel which it has been clamped against.

A further object of the invention is the provision of a clamp which is of such arrangement that it may be made out of stock steel and of such shape that its resiliency will be imparted without any special heat treatment or tempering, in order that it may serve the purpose desired.

A still further object of the invention is the simple method of assembly of the clamp on the head by which after adjustment may be minimized.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is either a top plan or side elevation of the beam, both views being substantially identical.

Fig. 2 is an end view of the beam head with the barrel in section on substantially line 22 of Fig. 1.

Fig. 3 is a perspective view of two of the clamp sections which I provide on the beam head.

Fig. 4 is a perspective view illustrating the method of positioning the clamp on the head for welding it in position.

It is desirable in the use of a loom beam that adjustable heads be of such construction that when the binding means is loosened, it will not be necessary to pry apart the sections of the clamp which engage the barrel, in order that the head may be moved axially along the barrel and in order that this may be accomplished in an inexpensive construction and yet one in which the heads of the beam will not bulge when the clamps are bound in clamping position, I have provided. a plurality of sections, preferably more than two, of identical construction with long resilient arms which are folded into overlapping relation, and are close to the arcuate body portion of the clamp and thus are as close to the center of the head as they may be positioned so as to prevent strains on the head when the sections are in clamping position which might tend to distort or bulge the head from shape; and the following is a more detailed description of the present embodiment of this invention and the method which I use for securing .the sections in place by which these advantageous results are accomplished:

With reference to the drawing, I 0' designates the barrel of the. beam which is providediwith trunnions I l at either end and upon which there. is mounted a pulley l2 which may be used for applying friction or tension on the beam. Upon this beam it), there are mounted heads designated generally I3 which are of identical construction and are adjustable along the beam. Each of these heads consists of a disk M of circular shape which may or may not be stiffened up as occasion requires. This disk I4 has a central opening l5 for the reception of the barrel l0.

In order that this head may be clamped in different desired positions along the barrel, I have provided a plurality of arcuate sections, preferably more than two, which I have illustrated as four in number. Each section comprises an arcuate body l5 of a substantial width which is provided with radial flanges I6 and I! from which there extend arms l8 and I9 considerably narrower than the width of the section l3 and which are bent as at 20 and 2| to extend back over the section [5, as illustrated in Figs. 2 and 3. This section is thus of all one integral piece of stock shaped down so as to provide relatively stiff and resilient portions dependent upon the thickness of the stock of which it is formed.

These sections are secured to the head by welding the arms at their end portions, as shown at 22 and 23, thus leaving the major length of each of the arms and the arcuate portion l5 of each section unattached to the head and capable of movement relative to the head by flexing of these long arms I8 and [9 when force is applied to flex them.

By reason of the pair of arms extending as illustrated and being secured as mentioned, a balanced relation is provided by which the sections may yield to move substantially toward and from the axis of the beam. This radial movement is brought about by the provision of bolts 24 having heads 25 and nuts 26 which extend thru registering openings 21 and 28 in the flanges l6 and ll of adjacent sections and which when taken up evenly will cause the sections to move evenly to grip the barrel along an extended portion of its surface and firmly secure these heads in adjusted position and by reason of the unattached extent of the arcuate portion l5 of the section and the unattached extent of the arms is and i9, each of these arcuate sections may be shifted to change its position sufficiently so as to accommodate it to the barrel and firmly engage the same over an extended surface to secure it in position.

In securing the sections in position on the head, I am enabled to lay the head flat upon some surface such as 30 with a circular post 3| extending at right angles therefrom and to then assemble the plurality of sections which are to complete the circumference about the barrel in their desired position against this post and to temporarily hold them in this position while securing the arms by welding, 22 and 23, at their ends to the head, thus at the time of welding I align the sections so that they present a substantially true circle which eliminates the necessity of aligning these sections after they have been assembled on the head, which latter is a more difficult operation and one requiring a high degree of skill. I

The foregoing description is directed towards the method and construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the equivalent changes to which the construction and method are susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. In a loom beam, a barrel, a head on said barrel, means on said head for clamping it in adjusted position along said barrel, comprising a plurality of identical sections, each having a movable body with a pair of resilient arms extending outwardly from the body and then toward each other, said arms being secured adjacent their ends to said head.

2. In a loom beam, a barrel, a head on said barrel, means on said head for clamping it in adjusted position along said barrel, comprising a plurality of identical sections, each provided with resilient arms at each end extending outwardly from the body and then toward each other, said arms being secured adjacent their ends to said head, and means for flexing said arms to place the same under tension and move the body sections toward the center.

3. In a loom beam, a barrel, a head on said barrel, means on said head for clamping it in adjusted position along said barrel, comprising sections provided with resilient means tending to separate the sections, and means for moving the sections toward each other to clamping position, said resilient means comprising a pair of resilient arms on each section folded to extend back along the section and in overlapping relation. a

4. In a loom beam, a barrel, a head on said barrel, means on said head for clamping it in adjusted position along said barrel, comprising arcuate sections of substantial width having integral elongated reduced resilient arms folded back upon the sections and secured to the head, and means to move the sections together into binding relation on the barrel and to place the arms under tension tending to move the sections outwardly.

35 5. In a loom beam, a barrel, a head on said.

barrel, means on said head for clamping it in adjusted position along said barrel, comprising arcuate sections of substantial width having integral elongated resilient arms of narrower width folded back upon the sections and secured to the head relatively close to the center thereof, and means to move the sections together into binding relation on the barrel and to place the arms under tension tending to move the sections outwardly.
